Now comes the fun part; we need to set up the for loop, which using the iterator “i” will iterate through the array’s contents and perform the display function. You can do it as such: This line sets up the loop. With the “$” symbol, we are specifying that we are trying to ...
For example, here's the array namedarrVarthat I want to work with: arrVar=( "1" "2" "3" "4" ) So if I add my variable name in the loop, the final version would look like this: #!/bin/bash arrVar=( "1" "2" "3" "4" ) #Loop part for (( i=0; i<${#arrVar[@]...

在Bash For Loop中使用“Continue”语句 “ continue ”语句是控制脚本运行方式的内置命令。除了bash脚本之外,它还用于Python和Java等编程语言。continue语句在满足特定条件时停止循环内的当前迭代,然后恢复迭代。可以看看如下所示的for循环。 #!/bin/bash
Bash For Loop Array Example The@operator accesses or targets all the elements. This makes it possible to iterate over all the elements one by one. In addition, you can access a single element by specifying its position within the array. ...
‘for’ loop can be used without any list or array or command output. How you can use ‘for’ loop to read command line arguments is shown in this example. Create a file named, ‘forloop10.sh’ and add the following script. The loop will iterate based on the number of command line...
